To aZZ whom, it may concern,.-

Be it known that I, WILLIAM LUDEWIG UHLENHART, a'. citizen of the United States,

residing at Astoria, in the county'of Clatsop, Oregon, have invented a new Car-Coupler, of which the following'is a specification.

My invention relates to an improvement of the fastening of the link by substituting a tongue or catch in place of the ordinary pin, with a spring to hold the catch in place; also, a lever with a hand-hold on top or side of car, by which the spring may be drawn back and the tongue or catch allowed to drop out'in uncoupling. In coupling, the link passes down the catch or tongue until the end has passed over it, when the tongue or catch is thrown by the spring through the link. I attain these objects by the said mechanism as illustrated in the accompanying drawings, in Which- Figure l is a vertical section of the whole coupling apparatus. Fig. 2 is a horizontal section of the coupling apparatus. Fig. 3 is a cross-section of link with tongue in position. Figli is a side lever for uncoupling.

Similar letters refer to similar parts throughout the different views.

A represents the coupling shaft.

B represents the coupling pin or tongue. C represents the lever.

D represents the link for coupling.

E representsthe fender-plate.

F, Fig. 4, represents lever-handle.

a represents bolts and pins. Y

b represents hand-hold to lever. d represents spring, r bber, or other mate'- rial. f

e represents lever spring.

The coupling pin or tongue B turns on the lbolt a, and is pressed down by the entranceof the link D until the end of the link passes-over' it, when the lever by the action of the spring y e raises the tongue B through the link D and locks it until withdrawn by means of the handholdsb and F.

b is intended to be operated from top of platform or ear.'

F is'to be operated from side of car.

3. In a car-coupling, the combination of the several parts, lever-pin B, lever C, fenderplate E, spring d, lever-spring e, and leverhandle F, all substantially as set forth.
